TRACTOR WHEE.. p

Appcation mea Febrary 23, 1927. Serial No. 170,303,

'The present invention is directed to an improved vehicle wheel which, in the present instance, is restricted more particularly to a tractor Wheel construction;

Briefly, the invention comprises a central flanged hub having radiating inter-connect` ed yokes, the bight portions ot which are especially shaped to provide 4 anti-slipping lugs, to make t'or inounting ot anti-slipping and traction bars, and to provide a central inwardly depressed portion. r

An important :feature of inprovement is the peculiar configuration ot the .so-called yoke members which have their bights constructed to provide opposite anti-slipping lugs and an intervening depressed portion, the latter serving to straddle a ridge while the lugs engage 'the'i urrows on opposite sides of the ridge, this being permitted when the traction bars are removed.

.An equally important feature is in a construction of this character wherein traction bars may be placed in position or removed at leisure to permit etlicient running` and traction on completely fiat surface or on a furrowecl surface, whichever is desired.

Other structural features and advantages ot' the invention will become apparent from the following description and drawings.

In the accompanying drawings forming a part of the application and in which like numerals are employed to designate like parts throughout the samek- Figure l is a side elevation of a traction wheel constructed in accordance with the in- Vention showing the right angular traction bars in place on the tread.

Fig. 2 is a similar view with the traction bars removed.

'Fig, 3 is a fragmentary section through the construction shown in Fig.-l. 4

Fig. lis a like View through the construction shown in Fig. L a Fig. 5 is a fragmentary top plan of the tread ofthe wheel asrepresented with the ti-action bars in place.

Fig. 6 is a detail tl'ragmentary view showing the spacing sleeves between portions ot' the yoke member.

Attention is first invited to Fig. l, wherein it will be seen that the reference charac-v ter 1 designates a hub including a tube having outstanding flanges 2 at its outer ends, these flanges being ot Circular torniand of appropriate diameter; Bolted or otherwise conn cted to the peripheralportions ot these 'as an 'arch to straddle the row.

flanges 2 are the yoke members which are generally designated by the 'reference characters 3. A suitable number of these :yoke members are employed and connected to the flanges so that they radiate therefrom in a manner shown plainly in Fig. l. i

Each member is formed from a single strip of metal ot appropriate gauge, the strip being preferably fiat. It will be noticed that the intermediate portion ot'` the strip is bent to provide a substantially U-shaped part l which operates as an arch and is adapted to override a ridge in a planted field. This U-shaped part is composed ot a. pair of arms 5 anclconnecting portions 6. lncidentally, the connectng portion is connected to a pair ot inner rings 7, the con nection being made by tlat sturdy strips 8 which are bolted in place shown.

At the arms 5, the end portions of the metal strips or straps are directed later-ally outward as at 9 and theseportions are bolted to a pair of symmetrical outer rings 10 which are disposed somewhat in alinement with the flanges 2. These ringsvare preferably of right angular cross section. Here the strip ends are bent outwardly and upon themselves as at 11 to 'form anti slipping lugs of the proportions represented. After the strap ends are formed into these lugs 11, then they are bent inwardly and into paral lelism with the atoresaid arms 5 to provide attaching arms 12, which are bolted as at 13 to the flanges 2. In this connection, it Will be noticed that bolts l- (see Fig. 6) are eX-' tended through the arms 5 and 12, and spacing sleeves 15 are arranged tl'ierebetween.

Obviously, this is to make the structure rigid. In this particular embodiment, it is plain,

Then the strap portions 9 on the opposite sides thereof provide a good 'and firm bearing; surface;

In 'addition, the lugs ll operate to guard against slipping and to provide eflicient traction. p V In cases where the wheel is operated on substantially fiat ground, having no rows and 'turrows, l prefer to add the traction bars 16 (see Figs. 3 and 5). tend diagonally with respect to the longitudiual axis of the tread. They are of right angular form, and obviously operate somewhat in 'the manner of the ordinary traction plates on tractor wheels.

YVhen in place, they bridge thearches 4.

that the U-shaped portion cooperates' These bars eri From the foregoing description and drawings, it wil] be seen that I have evolved an exceptionally novel. and simple, and inexpensive tractor Wheel of a convertible type, the same being usable in connection With a fiat surface or a fun-owed surface. ln either instance, a good and firm traction is provided, and slipping is substantially prevented. As the costruction is quite plain, the advantages are also apparent. Therefore, a more lengthy description is thought unnecessary.

Having thus described my inx'ention, What I claim as new is 1. In a tractor Wheel construction of the class described, a hub comprising a tube having outstanding flanges at its opposite ends, a plurality of radiating circumferentially spaced Voke members, each voke niember being formed from a single strap of metal, a pair of outer rings, a pair of inner rings, the end portions of the bight of each yoke being' fastened to the outer rings, the central portion being arched inwardly and t'astened to the inner rings, the end portions of the straps being directed outwardly and bent upon themselves to provide anti-Slipping lugs and attaching arms, the free ends of the attaching arms being fastened to said flanges.

2. In a tractor wheel construction of the class described, a hub comprising a tube having outstanding fianges at its opposite ends, a plurality of radiating circun'ferentially spaced yoke menbers, each yoke nen'- ber being formed from a single strap of metal, a pair of outer rings, a pair of iner rings, the end portions of' the bight of each yoke being fastened to the outer rings the central portion being arched inwardly and 'fastened to the inner rings. the end portions of the straps being directed outwardly and bent upon themselves to provide anti-Slipping lugs and attaching arms, the free ends of the attaching arms being i'astened to said fianges, and a plurality of circumterentially spaced diagonally disposed traction bars of right angular form detachably connected with said outer rings and bight portions of said voke members;

In testimony Whereof I aflix my Signature.
